Susan G. Buto, Rebecca Anderson
2020, Fact Sheet 2020-3033
Reliable and accurate high-resolution mapping of the Nation’s waters are critical inputs to models and decision support systems used to predict risk and enable response to impacts on water resources. It is necessary to know where the water is and how it relates to features beyond the stream network like...
Hydrodynamic modeling results showing the effects of the Luce Bayou interbasin transfer on salinity in Lake Houston, TX
Erik A. Smith, Sachin D. Shah
2020, Texas Water Journal (11) 64-88
An overreliance on groundwater resources in the Houston (Texas) metropolitan area led to aquifer drawdowns and land subsidence, so regional water suppliers have been turning to surface water resources to meet water demand. Lake Houston, an important water supply reservoir 24 kilometers (15 miles) northeast of downtown Houston, requires new...
A newly emerging thermal area in Yellowstone
R. Greg Vaughan, Jefferson Hungerford, Bill Keller
2020, Frontiers in Earth Science (8)
Yellowstone is a large restless caldera that contains many dynamic thermal areas that are the surface expression of the deeper magmatic system. In 2018, using a Landsat 8 nighttime thermal infrared image, we discovered the emergence of a new thermal area located near Tern Lake on the northeast margin of...

Wildland fires have a multitude of ecological effects in forests, woodlands, and savannas across the globe. A major focus of past research has been on tree mortality from fire, as trees provide a vast range of biological services. We assembled a database of individual-tree records from prescribed fires and wildfires...

Turtles and tortoises (chelonians) have been integral components of global ecosystems for about 220 million years and have played important roles in human culture for at least 400,000 years. The chelonian shell is a remarkable evolutionary adaptation, facilitating success in terrestrial, freshwater and marine ecosystems. Today, more than half of...

Balancing fish-energy-cost tradeoffs through strategic basin-wide dam management
Cuihong Song, Andrew O’Malley, Joseph D. Zydlewski, Weiwei Mo
2020, Resources, Conservation and Recycling (161)
Dam management often involves tradeoffs among hydropower generation capacity, environmental impacts, and project costs. However, our understandings of such tradeoffs under a full range of dam management options remain limited, which hinders our ability to make sound and scientifically defensible dam management decisions. In order to assess the scope for...
The influence of hunting pressure and ecological factors on fecal glucocorticoid metabolites in wild elk
David C. Ensminger, Catharine Pritchard, Tracy Langkilde, Tess Gingery, Jeremiah E. Banfield, W. David Walter
2020, Wildlife Biology (2)
Climate change and human population growth have increased anthropogenic threats to biodiversity and habitat fragmentation. Ecologists and conservationists need tools to assess the effect of these ecological and environmental perturbations on organismal fitness. One possibility is glucocorticoids (e.g., cortisol and corticosterone) which integrate various factors such as anthropogenic disturbances, predation,...
Effects of harmful algal blooms and associated water-quality on endangered Lost River and shortnose suckers
Summer M. Burdick, David A. Hewitt, Barbara A. Martin, Liam N. Schenk, Stewart A. Rounds
2020, Harmful Algae (97)
Anthropogenic eutrophication contributes to harmful blooms of cyanobacteria in freshwater ecosystems worldwide. In Upper Klamath Lake, Oregon, massive blooms of Aphanizomenon flos-aquae and smaller blooms of other cyanobacteria are associated with cyanotoxins, hypoxia, high pH, high concentrations of ammonia, and potentially hypercapnia. Recovery of the endangered Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes...
Habitat associations and distributions of two endemic crayfishes, Cambarus (Erebicambarus) maculatus Hobbs & Pflieger, 1988 and Faxonius (Billecambarus) harrisonii (Faxon, 1884) (Decapoda: Astacoidea: Cambaridae), in the Meramec River drainage, Missouri, USA

2020, Article
Understanding the habitat associations and distributions of rare species is important to inform management and policy decisions. Cambarus (Erebicambarus) maculatus Hobbs & Pflieger, 1988, the freckled crayfish, and Faxonius (Billecambarus) harrisonii (Faxon, 1884), the belted crayfish, are two of Missouri’s endemic crayfish species. Both...
Divergent biotic and abiotic filtering of root endosphere and rhizosphere soil fungal communities along ecological gradients
Candice Y Lumibao, Elizabeth Kimbrough, Richard Day, William H. Conner, Ken Krauss, Sunshine A Van Bael
2020, FEMS Microbiology Ecology (96)
Plant roots assemble two distinct microbial compartments: the rhizosphere (microbes in soil surrounding roots) and the endosphere (microbes within roots). Our knowledge of fungal community assembly in these compartments is limited, especially in wetlands. We tested the hypothesis that biotic factors would have direct effects on rhizosphere and endosphere assembly,...
3D fault architecture controls the dynamism of earthquake swarm
Z. Ross, Elizabeth S. Cochran, D. Trugman, Jonathan D. Smith
2020, Science (368) 1357-1361
The vibrant evolutionary patterns made by earthquake swarms are incompatible with standard, effectively two-dimensional (2D) models for general fault architecture. We leverage advances in earthquake monitoring with a deep-learning algorithm to image a fault zone hosting a 4-year-long swarm in southern California. We infer that fluids are naturally injected into...
Using reproductive potential to assess oyster population sustainability
Danielle A. Marshall, Samuel C. Moore, Malinda Sutor, Jerome F. La Peyre, Megan La Peyre
2020, Restoration Ecology (28) 1621-1632
Ensuring that oysters remain sustainable in the face of significant coastal restoration activities, high local subsidence rates, and predicted sea-level rise requires a deeper understanding of basic population demographics, including reproductive potential. We quantified fecundity (eggs ind−1) of oysters at high- and low-salinity sites during a fall and spring spawn...
Envisioning a multi-agency and multi-academic institution geomorphology data exchange portal
Molly S. Wood, Paul M Boyd
2020, Open-File Report 2020-1056
Access to bathymetry and geomorphology data for rivers and reservoirs is a critical need in multiple agencies and academia. These data are needed to make water-resource-management decisions regarding river restoration, resource protection, infrastructure design and sustainability, and flood-risk reduction, and during natural disasters. Sharing of data increases decision-making capacity by...
Colonisation of the alpine tundra by trees: Alpine neighbours assist late-seral but not early-seral conifer seedlings
Meredith D. Jabis, Matthew Germino, Lara M. Kueppers
2020, Plant Ecology & Diversity (13) 209-224
BackgroundClimate change is projected to alter the elevation and latitude of treeline globally. Seed germination and seedling survival are critical controls on treeline expansion. Neighbouring alpine plants, either through competition for resources or through altered microclimate, also affect seedlings emerging in the alpine zone. With warming,...

High-magnitude storm events such as Hurricane Sandy are powerful agents of geomorphic change in coastal marshes, potentially altering their surface elevation trajectories. But how do a storm’s impacts vary across a large region spanning a variety of wetland settings and storm exposures and intensities. We determined the short-term impacts of...
Changes in conservation value from grasslands to savannas to forests: How a temperate canopy cover gradient affects butterfly community composition
Ralph Grundel, Gary S. Dulin, Noel B. Pavlovic
2020, PLoS ONE (15)
Temperate savannas and grasslands are globally threatened. In the Midwest United States of America (USA), for example, oak savannas persist today at a small percentage of recent historic coverage. Therefore, restoration of habitats of low and intermediate canopy cover is a landscape conservation priority that often emphasizes returning tree density...
